Stuart Davies: All transmitters in your area carry HD services as they have switched fully to digital.

Any prediction system of where signals are available which are based on post codes should be taken with a pinch of salt. They exist because of the demand for such a service and not because they can ever be in any way totally accurate.

Stuart - I live in Buckley and can receive Freeview HD from both Winter Hill (C54) and Storeton (C60) which gives me BBC1, BBCHD, ITV1, C4 and S4C Clirlun, all without problem.

Now that improvements have been made to the coverage area maps, I can now see how poor the coverage area actually is in North-East Wales, which Moel-Y-Parc is supposed to serve. It appears to have almost the same coverage area as Winter Hill with more coverage in England and barely any coverage in Wales.

Therefore I'm wondering if the radiation patterns and/or powers of either or both masts should be changed to prevent so much of an overlap and for Moel-Y-Parc to transmit less power to Lancashire, Greater Manchester, Merseyside and Cheshire and more power to Flintshire, Wrexham, Denbighshire and Conwy?

You would think though a town the size of Wrexham and also with the importance Llangollen has on the world with the International Eisteddfod, that both places should be entitled and therefore able to receive the Main transmitter for North-East Wales.

So I've often thought perhaps Moel-Y-Parc at Postcode CH7 5UU maybe wasn't the best location for the transmitter, maybe somewhere higher up towards, or better still, on the Clwydian Range mountains may have been better or maybe if the mast was made taller or more powerful towards the Welsh counties it's supposed to serve and less powerful towards English counties which it's not supposed to serve.

It will be interesting to hear other people thoughts and take on this.

Stuart O.: It's consistent with the analogue coverage area published in the IBA's old guides. See mb21 - Transmitter Information - Moel-y-Parc .

The overspill into England is just a consequence of the height-above-ground and the relative low heights of the terrain there. North Wales is just too folded for the signal to get down into the valleys, so numerous relays are required. Even VHF, which bends better over terrain than UHF, was tricky: see mb21 - - ITV 405 line TV Transmitters - Wales and W England .

This website doesn't have access to the radiation patterns for most of the main transmitters, so it assumes equal power in all directions. It's very likely that power is reduced to the east, to reduce interference into England. We already have to clear Moel-Y-Parc with the Irish authorities to ensure it won't interfere too much with their services, so a power increase is likely out of the question.

Mike Dimmick: Even the analogue coverage shouldn't have had that much overspill across the borders in my opinion.

All I'm saying is if you look at the coverage of the Moel-Y-Parc transmitter, it doesn't appear to serve that many people in Wales in its designated service area. It appears to serve more people in the North West than to Wales itself which is why I'm saying the aerials on the mast should be directed less at the North West and more around the aforementioned counties in Wales.

If it can't be done by increasing the power, then it couuld've been done had the transmitter been built taller or at a higher location above sea level than present.

Another thing I was wondering, should ArqA now show as having a power of 12,500 Watts?, not 10,000 Watts?

The notes above say:
ArqA increases from 10kW to 12.5kW on 28 September 2011. (changes to 64QAM mode and loses its current +167kHz offset.)

Would anyone be able to get back to me with my query above please?
I've noticed no-one has replied and usually Briantist, Mike Dimmick, Dave Lindsay and jb38 usually get back to me quite quickly after I post a message so it would be nice if one of you or someone else could get back to me soon.

Kind Regards,
Stuart O.

Stuart O.: Refer to the Digital Terrestrial Broadcasting Stations for Multiplex Licences Version 7 27 January 2012:


For Moel y Parc, 51 (SDN) and 52 (ArqA) are 10kW. 48 (ArqB) is also 10kW but "Until 24 October 2012, services are subject to a
reactive power restriction of 5,000 Watts".

What is a reactive power restriction anyway?
Is it permanently at 5,000 Watts until 24th October or are there periods when power is increased?
I'm seeing powers mentioned of 10,000 Watts, 12,500 Watts and 5,000 Watts and can't make out which multiplexes have been on or are on or due to be on each of the power ratings I have stated above.
And why mention 12,500 Watts from 28th September 2011 when in actual fact it's at 5,000 Watts?

I live in Gwynfryn and cannot receive any of the Welsh channels. Why is this?
